Replacement RT28080049 Front Right Steering Knuckle & Wheel Bearing Hub Assembly

The Replacement RT28080049 is a front right (passenger side) steering knuckle and wheel bearing hub assembly designed as a direct-fit OEM replacement for the Toyota Sienna. This unit serves both AWD and FWD configurations, as well as the 2.7L four-cylinder engine variant, covering model years 2011 through 2017.

Replacing a worn or damaged knuckle assembly restores correct wheel alignment, smooth steering response, and consistent handling.
